Nurfing is the act of adding random sluts within your area or in other area codes over myspace and facebook and getting their number and texting them. Once you get their number, you act like a super douche to them until the nude picture has been sent and then never talk to them again. Make sure that these sluts are at least 18, otherwise it is considered child porn.
